CVE-2016-8610

TITLE

OpenSSL  Service operation interruption in  (DoS)  Vulnerability

DESCRIPTION

A denial of service flaw was found in OpenSSL 0.9.8, 1.0.1, 1.0.2 through 1.0.2h, and 1.1.0 in the way the TLS/SSL protocol defined processing of ALERT packets during a connection handshake. A remote attacker could use this flaw to make a TLS/SSL server consume an excessive amount of CPU and fail to accept connections from other clients. It supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, security hashing algorithm, etc. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openssl security update Advisory ID: RHSA-2017:0286-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2017-0286.html Issue date: 2017-02-20 CVE Names: CVE-2016-8610 CVE-2017-3731 ===================================================================== 1. Summary: An update for openssl is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate.

This software, such as Apache HTTP Server, is common to multiple JBoss middleware products, and is packaged under Red Hat JBoss Core Services to allow for faster distribution of updates, and for a more consistent update experience. Security Fix(es): * A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support. (CVE-2016-6304) * It was discovered that the mod_session_crypto module of httpd did not use any mechanisms to verify integrity of the encrypted session data stored in the user's browser. (CVE-2016-0736) * It was discovered that the mod_auth_digest module of httpd did not properly check for memory allocation failures. (CVE-2016-2161) * A timing attack flaw was found in OpenSSL that could allow a malicious user with local access to recover ECDSA P-256 private keys. (CVE-2016-8610) * It was discovered that the HTTP parser in httpd incorrectly allowed certain characters not permitted by the HTTP protocol specification to appear unencoded in HTTP request headers. If httpd was used in conjunction with a proxy or backend server that interpreted those characters differently, a remote attacker could possibly use this flaw to inject data into HTTP responses, resulting in proxy cache poisoning. (CVE-2016-8743) * A vulnerability was found in httpd's handling of the LimitRequestFields directive in mod_http2, affecting servers with HTTP/2 enabled. (CVE-2016-8740) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-6304 and Shi Lei (Gear Team of Qihoo 360 Inc.) for reporting CVE-2016-8610. Upstream acknowledges Shi Lei (Gear Team of Qihoo 360 Inc.) as the original reporter of CVE-2016-6304. After installing the updated packages, the httpd daemon will be restarted automatically.

JIRA issues fixed (https://issues.jboss.org/): JBCS-319 - Errata for httpd 2.4.23 SP1 RHEL 7 7. Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. If sendfile processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647) * A vulnerability was discovered in the error page mechanism in Tomcat's DefaultServlet implementation. A crafted HTTP request could cause undesired side effects, possibly including the removal or replacement of the custom error page. Solution: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). CVE-2016-8610 It was discovered that no limit was imposed on alert packets during an SSL handshake. CVE-2017-3731 Robert Swiecki discovered that the RC4-MD5 cipher when running on 32 bit systems could be forced into an out-of-bounds read, resulting in denial of service. For the stable distribution (jessie), these problems have been fixed in version 1.0.1t-1+deb8u6. For the unstable distribution (sid), these problems have been fixed in version 1.1.0d-1 of the openssl source package and in version 1.0.2k-1 of the openssl1.0 source package. We recommend that you upgrade your openssl packages. 6) - i386, x86_64 3. The following packages have been upgraded to a later upstream version: gnutls (2.12.23). (CVE-2016-8610) * Multiple flaws were found in the way gnutls processed OpenPGP certificates. An attacker could create specially crafted OpenPGP certificates which, when parsed by gnutls, would cause it to crash.
